The 1939 Cancer Act in the UK (England & Wales) prohibits advertising of cancer treatments to the public, by anyone but the NHS. The rise of the internet and social media presents new challenges to its enforcement and raises questions about unintended consequences for patients being treated for cancer.

Through anonymous surveys, this study aims to understand how patients, healthcare professionals and industry professionals perceive technological changes and their implications for online and social media cancer care information, as well as highlight opportunities for safe and ethical modernisation.

This study will be inviting patients who have recently received treatment for cancer to participate in a single survey, about their experiences of online and social media information during their cancer journey and their views on the current law. Healthcare professionals who work with cancer patients will also be invited to participate in their own variation of this survey.

Inclusion Criteria:

• UK residents (England and Wales ONLY).
• Have been treated for a cancer within the last three years.
• Aged 18 or over.
• Can complete the survey themselves or have it completed on their behalf by a friend or family member (with the patient's permission).

• Aged 18 or over.
